  • a safety circuit for monitoring the safety functions of the welding system which, in addition to an ON operating state in which a welding process or a sequence of welding processes is made possible, allows at least one other OPERATING INTERRUPTION operating state in which the output voltages of the power supply device and the feed control device are at least blocked.
  • the invention further relates to a method for controlling such a welding system.
  • a short-time arc welding system and a method for short-time arc welding are generally known under the term “stud welding”, for example from a brochure “The new TUCKER technology. Stud welding with a system!, Published by “Emhart TUCKER”, September 1999.
  • the technology of stud welding is used in particular, but not exclusively, in automotive engineering. With this technology, bolts with or without thread, nuts, eyelets and other elements can be welded onto body panels. The elements then generally serve as holding anchors for attaching interior fittings, for example, to the vehicle body.
  • an element is first inserted into a welding head. This can be done by an automatic feed device, for example by means of compressed air. The element is now positioned at the appropriate point on the component with the welding head. Next, a pre-welding current is switched on, which flows through the bolt and the component. Then the element is raised in relation to the component, which forms an arc. The arc current is selected so that contaminants, surface coatings such as zinc, oil or dry lubricants etc. are burned off first. Then the welding current is switched over. Due to the high welding current, the opposite end faces of the element and component melt. The element is then lowered back onto the component so that the mutual melts mix. The welding current is switched off when the component reaches the component and the arc is short-circuited. The melt solidifies, with which the welded connection is established.
  • the element is raised and lowered relative to the component an electric motor, in particular by a linear motor, which causes a controlled movement of the element.
  • a control and energy device for energy supply and for controlling the welding process, a control and energy device is provided according to the aforementioned brochure, which has a power supply device for supplying energy to the welding head device, and a feed control device for controlling the supply of elements to be welded by means of the supply unit and for controlling the drive of the Has thrust control device for raising and lowering elements.
  • the control and energy device further comprises a safety circuit for monitoring the safety functions of the welding system, which, in addition to an ON operating state, in which a welding process or a sequence of welding processes is made possible, allows at least one further OPERATING INTERRUPTION operating state, in which the output voltages of the power supply device and the feed control device are at least blocked.
  • the invention is therefore based on the object of specifying an improved short-time arc welding system or an improved method for controlling such a system, which enables simplified maintenance of the system and simplified fault diagnosis, while maintaining a high safety standard.
  • the object of the invention is further achieved by a method for controlling a system for short-time arc welding of elements, e.g. Metal bolts, on metal parts, e.g. Metal sheets, solved, in which the elements are welded to the component by means of an arc using a welding head device while moving relative to the component, with the following steps:
  • a selective activation of individual components of the system is now made possible, a high security standard being ensured at the same time by the means for securing against the selective activation by unauthorized persons.
  • the power supply device cannot emit an output voltage since its output voltage is either blocked or it is separated from the mains. This ensures that welding processes can never be activated in the event of maintenance or diagnostic work.
  • a main switch which is designed as an EMERGENCY STOP switch, when actuated, the control and energy device is immediately disconnected from the mains voltage and is stopped.
  • At least the output voltages of the power supply device and the feed control device are blocked in the OPERATING INTERRUPT operating state, an operating mode selector switch secured against unauthorized use being provided, which is coupled to the safety circuit in order to selectively activate individual components of the system in the OPERATING INTERRUPTING operating state to enable.
  • the power supply device comprises a constant current source, the output voltage of which can be blocked via a pulse blocker circuit.
  • the pulse blocker circuit which is usually present in such welding systems, can be used to reliably block the output voltage of the power supply device, provided that individual components of the welding system are to be selectively activated in the event of a partial interruption in the event of maintenance work.
  • the pulse blocker circuit can be used to deliberately delay the welding process if the welding process is to be stopped.
  • control and energy device has a control device for controlling the welding system and an input device for inputting operating commands.
  • the welding head device can be coupled to an external operator control, via which a welding process can be activated in the ON operating state.
  • the welding head device can be meaningfully integrated into an external control of a manufacturing process.
  • control and energy device has a customer interface, which can be coupled to the external operator control, preferably via a bus.
  • the operating mode selector switch enables a switchover between the AUTOMATIC operating modes, in which the welding process can be activated in the ON operating state via the external operator control, and MANUAL OPERATION, in which at least the output voltage of the power supply device is blocked.
  • the operating mode selector switch is preferably coupled to an enabling button which, in the MANUAL OPERATING mode, allows manual activation of selected functions of the welding system with simultaneous activation of the external operator control in two-hand operation.
  • the enabling button in the MANUAL MODE can allow, for example, the feeding of elements by means of the feeding unit and the activation of a drive of the welding head device for raising and lowering elements.
  • the safety circuit has a further operating state OPERATOR PROTECTION, when activated the power supply device and the feed control device are delayed and disconnected from the mains, while the control device and the input device remain under protective extra-low voltage and the customer interface is supplied with voltage, whereby manual cancellation of the OPERATOR PROTECTION operating state leads to the ON operating state after a time delay.
  • This measure enables the control and energy device to be shut down safely in the event of a necessary stopping, for example when an operator opens a door of the control and energy device, without complications during an ongoing welding process, and at the same time a simplified restarting is possible.
